Are These the Top Book Marketing Services in the USA?

[RichardFox111]

I recently came across a list claiming to showcase the Top Book Marketing Services in the USA, but I want real feedback. Has anyone used Book Launchers, Smith Publicity, or Author Marketing Experts? I’m releasing a memoir soon and need help with both pre-launch and post-launch promotion. Things like social media ads, Amazon optimization, and media outreach are important. If you’ve had a great experience with any U.S.-based book promotion service, please drop your thoughts here. Let’s figure out who’s actually delivering results and who’s just selling hype.
